noon LATCH.

Application filed January 4, 1922. Serial No. 527,003.

To all whom t may concern:

Be it known that 1, lnviivo.` SoiNiinN'rHAn,

a citizen of Poland, and a resident o'l` New `York city, borough of Manhattan, in the 5 county and State of New York, haveinvented certain new and useful Improvements in Hook Latches, of which the following is a full, clear, and exact description. y

Among the principal objects `which the Vv present invention has in view are: to provide Aan improved hoolr latch Aover the one for. which a Patent No. 1,370,711 was grantf ed to me -fon March 8, 1921, cross reference to which is here made; to prevent ,the acci? dental release ofthe latch; to provide a strong, neat and'simply constructed latch of the character mentioned.'

Draw/ings.

structed in accordance with my present invention, the latch being shown in conjunction with the fragment of a wrist-band and watch, and in locked position.

' Description.

The latch herein disclosed is particularly adapted for use with wristbands vconstructed of ribbon or other iexible material and comprises essentially two separate parts, one ot which, the hooli member 10 is iiastened to the wristband 11 and the other or sliding member 12 of which is mounted to slide on the hook member 10.

1n developing the hook member 10 a Figure 1 is a plan view of a latch con- Figure 5 is a plan view of the latch shown.

metal stamping of the configuration shown in 141g. 7 having ribbon engaging slots 13 is shaped to provideaprojection which when bent up forms a hook 1e, and wings 15, the

edges of which when turned inwardly7 act as a guideway for the sliding member 12.

Rererring to Figure 8, the development of the sliding member 12 comprises a T-shaped stamping having arcuate wing portions 1G "formed at the junction oi 4the upright and 'tions 20 forming feet which are disposed beneath` the wings 15 oi' the hook member when assembled, the portions 21 forming the sides, 22 the top and'23 the back of said hood. When the bending has been done, a part of the upright of the T will form the bottom. rlfhe wings 16 are then bent against the portions 21 and their straight edges will be spaced slightly from the feet portions 20. This will allow the guide forming' wings 15v to lit therebetween.

The sliding member 12 thus formed, is assembled to the hook member 10 in posi-- tion sothat the hooked portion 17 on the former can be forced beneath the end of the hook 14 on the latter. This provides i'or a loclr because the space between the end of the hook 17 and the edge of the hood 12 will just permit the insertion therebetween of the watch ring 1S, so that when the hook 17 passes beneath the end of hook 14e, the ring can not be withdrawn.

In order to further lock the ring in place, a slight pull will cause the hood 12 to more forwardly, the top of it passing over the end oi' the hooli 14 and riding up on the top of said hook will bend it down suiliciently to prevent the hook 17 on the sliding member from being withdrawn.

The wings 15 are bent as at 2e to provide stops to limit the rearward movement of the sliding member land prevent its accidental separation from the hook member 10. The latch may be used in many services. One

service for which it is particularly adaptable is in conjunction with wrist or other watches inwhich a ribbon is the supporting means.

It will be observed that the normal tendency of the hood 12 and parts associated therewith is to assume the position Where the latch is closed, `and from which it Vis dilcult to remove by accident the watch ring 18.V
